Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed May 16, 1914. Serial No. 839,123.

To all whom it may concern:

Be it known that 1, JOHN D. SGHENK, a citizen of the United States, residing at Menno, in the county of Hutchinson and State of South'Dakota, have invented certain new and useful Improvements in Condensers and Vaporizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention, relates to condensers and Vaporizers and is more particularly adapted for use in connection with gas produc ing plants, and has for one of its objects the construction of a device for efficiently gencrating water into steam to be supplied to the gas producer, the water being heated by the heated products of the exhaust from the engine.

'A further object of this invention resides in the construction of a condenser and vaporizer with means for automatically supplying water thereto.

A still further object of this invention resides in constructing the heating plates in sections, whereby the same'may be readily taken apart for cleaning the same of scale formed therein, especially in the case when hard water is used. And a still further ob ject of this invention resides in the construction of a condenser and vaporizer consisting of few parts, readily assembled or taken apart as the case may be and which may be manufactured at a nominal cost.

These and other objects will more'fully appear and the nature. of the invention be more clearly understood by the construction, combination and arrangement of the parts thereof as described in the following specifications, defined in the appended claims, and illustrated in the accompanying drawings, in which,

Figure l is a side elevation of the invention, partly in section, showing the same in complete assembled form ready for use. Fig. 2 is a top plan view of one of the plate sections, and Fig. 3 is a vertical sectional view on line 33 of Fig. 2 looking in the direction of the arrow, showing the manner of connecting the sections thereof together and 'the manner of establishing communication between the respective plates.

Referring to the drawings, 1 denotes the outer casing, preferably cylindrical in form, 2 the elevated bottom therein, 3 the drain pipe secured in the plate 21 and in the bottom 2, and 4 the valve arranged in the drain pipe 3. The casing 1 is provided at points diametrically opposite each other with openings which are surrounded by interiorly threaded bosses 5 which are positioned at points substantially mid-way between thetop and bottom sections thereof with which engage the ends of pipes 6, one section of the pipe 6 conveying the exhaust from an engine (not shown) used in connection with any preferred make of gas producing plant (not shown) and the opposite section forming an exhaust port from the casing, and it will be understood that any number of intake and outlet pipes may be used around the casing as occasion may require.

Suitably mounted in the bottom. 2 of the casing 1 slightly removed from the inner wall thereof and secured in the bottom 2 by the nuts or other suitable means 7, are the supporting rods 8, it being understood that any number of rods 8 may be used, the up per ends projecting slightly above the upper edge of the casing 1 and provided with screw threads 9 thereon.

Arranged within-the casing 1 are a plurality of superposed hollow heating plates 10, the plates 10 being formed in two-part sections 11 and 12, each of the sections being provided with the alternately arranged spacing lugs 12 and also with the registering apertured securing ears 13 and secured together through the medium of the bolts 14 adapted to be passed through the apertures in the respective registering ears 13. The upper section 11 of each heating plate except the uppermost one, is provided with an opening 15 while the lower section 12 of each heating plate except the lowermost one,

is provided with an opening 16, the open-- ing 15 of one of the plates registering with the opening 16 of the next adjacent plate,

said pairs of openings 15 and 16 being alternately staggered relative to each other throughout the plurality of plates, this arrangementcausing the water to take a circuitous course through the respective plates to subject the same to a greater area of the heating surfaces of the plates.

Each of the sections 11 and 12 is provided with the central interior flange 1'7, the flange .17 of each of the sections 11 and 12 lying in the plane with the longitudinal medial division line of the plates 10 and each may be provided'with a gasket ring interposed between the meeting edges of the flanges 17. The flanges 17 encircle central openings 18 formed through the plates 10.

For establishing communication between each of the adjacent plates the unions 19 are provided, having arranged thereon the annular flanges 20, slightly removed from the ends thereof, to provide lips for passage in the openings 15 and 16 of the respective plate sections 11 and 12. I In assembling the plurality of heating plates 10 within the casing 1 it is to be noted that the lower wall of the lower plate is formed solid, as at 21, and that each of the plate sections is provided with the supporting ears 21' which ears engage the supporting rods 8 and are retained thereon at a point remote from the bottom 2 through the medium of the nuts 22 upon the threaded ends of the rods 8, the upper half of the lower plate being provided with the opening 15 as in the other plates, but also being further provided with the centrally arranged and upwardly extending screw threaded'boss 22', into which is threaded the vertical pipe 23', passing upwardly through the central apertures 18 of the superposed plates 10 and projecting above the casing 1, as at 23, and upon the upper end is secured the union 24: to which is connected the pipe 25 'for conveying the steam, air or vapor from within the vaporizer to the gas producer plant, not shown, a suction pump or other means (not shown) being connected to the pipe 25 for positively removing steam air or vapor from the vaporizer as rapidly as it is produced or entered thereinto.

It is to be'noted that the upper half 11 of the uppermost plate 10 is provided with the annular rib 26, which ribis provided with the right angular flange 27 for embracing the upper edge of the casing 1, to provide a top therefor, the rib 26 being suitably apertured for engaging the ends of the supporting rods 8 and retained-upon the casing 1 through the medium of the nuts 28 threaded upon each of the ends 9 of the rods 8.

Upon the uppermost section 11 and suitably connected thereto, is the water, air or other fluid pipe 29 in'which is arranged a suitable valve 30 and from which extends the supply pipe 31, which pipe is connected to any suitable source of fluid supply (not shown), the valve 30 being provided with the operating lever 32, to the free end of which is connected the curved piston rod 33 of the piston 34: operating within the curved cylinder 35, suitably mounted in the wall of the section 11 of the uppermost heating plate 10.

In this device the water or other products are admitted into the vaporizer in such quantities as to be condensed into steam or thoroughly heated by the time it reaches the lowermost section or heating plate and as the steam or other products are drawn through the pipe 23 from the lowermost heating section as rapidly as it is produced, vacuum or suction will be caused in the uppermost section which will tend to move the piston 34 inwardly and open the valve 30,

but should the suction pump cease to work tion through the pipe,23'- is restored, the

valve will again be opened and the supply 0 fluid or air restored.

' From the foregoing it is obvious that I have invented a condenser and vaporizer which may be readily taken apart for the purpose of cleaning and at the same time have provided an efficient structure, whereby the water or other fluid supply is auto matically fed to the same by the suction in the pipe 25 caused by the engine, pump or other suitable means (not shown) and which suction drawing the steam, or vapor, from the lowermost plate 10 necessarily causes a vacuum in the uppermost plate and, in this instance, the vacuum draws the piston 34:, within the cylinder 35, inwardly, this movement operating the valve 30 and the water, air, or other fluid, conveyed through the pipe 31 is readily drawn into the condenser and vaporizer, the fluid being intensely heated by the heated exhaust within the casing 1, and if the fluid be in the nature of water, the same is generated into steam by the time it reaches the lowermost plate, wherein the same is capable of being drawn through the pipe 23 and upward through the lead pipe 25 to the gas producingplant.

While I have shown the preferred embodiment of my invention, the right is hereby reserved to make such alterations and variations therein as I may, deem expedient from time to time and which will not depart from the spirit of this invention nor conflict with the scope of the claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is:

1. A heating device comprising a hollow casing, an elevated bottom section in said casing, vertically disposed rods having threaded lower and upper ends, means to secure the lower ends of the rods to said bottom, a plurality of hollow heating plates arranged one above the other and communicating with each other, ears on each section engaging said rods, means on said lower threaded portion of said rods to direct upward pressure on said heating sections and hold the same in juxtaposition to each other, an annular rib integral with the uppermost v a plurality of superposed cooperating heat-- heating plate, said rib forming a top for said casing, an annular depending flange adapted to engage andeXtend over the upper end of the casing, means engaging the upper ends of said rods to lock the rib in engagement with the casing, an escape pipe communicating with the lowermost heating plate and extending vertically through the remainder of said plates, and means to con-- vey fluid into said heating, plates.

2. A heating device, the combination with ing plates having an escape pipe communicating with the lowermost heating plate, of

a supply pipe communicating with the upv e lie permost heating plate, a valve cooperating with said supply pipe, a cylinder communicating with the uppermost heating plate, a piston in said cylinder and connected with said valve, said piston being operated by the pressure in said heating plates, to open or close said valve.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
